Air Fryer biscuit donuts are so quick and easy to make! These biscuit donuts only take 5 minutes to cook and turn out soft and fluffy on the inside while coated in a cinnamon sugar crust on the outside.
Add cinnamon and sugar to a medium bowl. Stir to combine. Add milk to another medium bowl. (Note - both bowls should be large enough for dipping donuts).
Preheat air fryer at 360 degrees F for 5 minutes.
Open your can of biscuits and punch a hole in the center of each one using a donut cutter. Dip each donut on both sides in the milk, then in the cinnamon sugar mixture. Repeat for all donuts.
Add parchment paper to air fryer (if using) and place donuts in air fryer basket. (I did two batches- 4 at a time).
Air fry for 5 minutes at 360 degrees F. Remove from air fryer and enjoy.
Notes
For a less sweet version of the donuts, only dip one side in the cinnamon sugar mixture.
Do not add parchment paper to the air fryer while preheating.
You may need to cook in multiple batches depending on the size of your air fryer.
